I did this and started only loading OA. My computer illiterate self will just keep playing OA for now. Thank you very much for the help. :-)

Thank you for the quick response! My line 26 says this: "%_STEAMPATH%\steam.exe" -applaunch 33930 "-mod=%_ARMA2PATH%;EXPANSION;ca" I tried adding it in spite of the fact it's different, but it gave me an error message.

Can someone tell me how to load this with the CO script? I tried this: "C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\_runA2CO.cmd" -noSplash -mod=@CBA;@CBA_OA;@ACE;@ACEX and it doesn't work.

I have CD installed ARMA 2 and Steam installed OA. I can load CO by right clicking on OA in steam, but can find anyway to make a shortcut for it so I can install ACE etc... for CO. I'm pretty computer illiterate. I'm sorry if this has already been answered. Thanks! :)
